BE VIE W 

Cadien (in) Straughan & Klink (1980) 

A very useful list of opisthobranch species "Known" (?) from the southern California 
bight. As this document qualifies as formal journal publication, I am compelled to point 
out several severe problems in the opisthobranch section. They are undocum ented and 
unsupported synonymies of two species: Aplysiopsis enteroi orphae (Cockerel! i Eliot, 
1905) = Aplysiopsis smitfai (Marcus, 196 1) = Pnyllobranchopsis enterona orpcae C. & E. 
Flabellinopsis iodinea (Cooper, 1862) = Coryphella sabulicola Co wen & Laur, 1978. 
Although I tend to agree with the latter, an explanation of the basis for these changes ' 
would certainly be preferable; and, many species included in the list are of questionable 
status and have avoided collection and/or documentation since originally described. This, 
of course, is a reflection upon the need for a little "formal" house cleaning zn many of 
our older species, particularly those of the Bullomorpha. 

* 

To my knowledge, this may be the first "formal" reference to Tritonia diosedea as ; 
senior synonym to T. exsulans, although Thompson (1971) did imply it. 

Many new species are known from the bight, however, only one is listed here, 
Cadiens's Rumcinida sp. (?) 

Because this document is not widely available, two points of interest should be noted: 
a) the range extension of Alderia -m odesta from Elkhorn Slough to Newport Bay, 
California, 300 miles, and b) although dropped by Smith & Carlton, 1975, Aglaja nana's 
range is extended from San Francisco Bay to Newport Bay, California, 375 miles. Does 
this mean that A. nana is still valid? Other than these oversights, a formidable work. — 
Dave Behrens. 

FO R SALE 

Dave Behren's book entitled "Pacific Coast Nudibranchs" is still available frc ~ the 
OPISTHOBRANCH NEWSLETTER at $14.95 plus $1.00 for shipping. California residents 
must add appropriate sales tax. A review of this book appeared in the San Luis Obispo 
TELEGRAM-TRIBUNE on Saturday, December 20, 1980 which includes a picture of Dave 
and of Chro mod oris macfarlandi. About 2000 copies of Dave's book have beer, sold to 
date. 

READER REQUESTS 

Howard Katzman wants information on Arctic and Antarctic biology including unpublished 
photos. Howard is a Los Angeles teacher and is working on a paper for schccl including 
possible publication. Contact him at 2043 Veteran Ave., Los Angeles, CA 90025. 

Bob Burn wants a few preserved specimens of Cylichnella inculta (Gould, IB 55) to 
compare with local fauna found in Australia. He would like to obtain any of the 
Calif ornian bullomorphs in exchange for similar Australian material or nudibranchs.

A COLOR VA RIATION IN 
DORIDACEA). by David W 



CHROMODORIS MACFARLANDI ( N U DIB R A N C HIA 
Behrens, 416 Lilac Drive, Los Osos, CA 93402. 



Personal observations of a large number of specimens and literature concerning 
the cryptobranch dorid nudibranch Chrom odoris m acfarlandi Cockerell, 1901 has shown 
the characteristic notal striping to be highly consistent. Color descriptions by Cockerell 
(1901), MacFarland (1966), Keen (19-71), McDonald (1977) and Behrens (1980) indicate a 
body color of deep violet with three solid yellow to cadmium orange longitudinal 
stripes. The median stripe begins about half way between the anterior margin of the 
notum and the rhinophores. and continues posteriorly to the branchial sheath. The 
midlateral pair begin just behind the rhinophores and pass posteriorly midlaterally, 
encircling the branchial pocket, where they unite. MacFarland (1966:155) reports that 
in one specimen several scattered small spots of yellow were observed on the m antly 
behind the gill and the union of the lateral stripes were prolonged posteriorly into a 
broad point, the tip of which was encircled by the above spots. Reported here is an 
additional yet more pronounced example of this color variation.

Figure 1: Chro mod oris m acfarlandi, Cockerell, 1901 

On November 3, 1979,. a variant colored individual of C. m acfarlandi was collected 
by Mr. John Warrick, Pacific Gas and Electric Company, while conducting intertidal 
surveys in Diablo Cove, San Luis Obispo County, California (figure 1). The specimen 
measuring 40mm in length, was marked by quite irregular midlateral striping. Typical 
in all other characteristics, the midlateral stripes were broken into a series of 
scattered irregular yellow spots. Less dense anteriorly, the spots formed an irregular 
stripe posteriorly. Although never actualy stated in the above color descriptions, the 
midlateral stripes are always with this exception smooth and unbroken.

CALL FOR SPECIMENS 

Currently there are some 30 undescribed species of opisthobranchs. on the west coast 
alone. Most of these species are in the process of being described by one or more 
researchers. Specimens, photographs, and all types of biological and ecological 
information are welcomed by those trying to describe them. This section will contain 
preliminary information (not descriptions) along with names of anyone known to be 
working with the animal. The intent is absolutely NOT to describe anything new to 
science here. I am hopeful that knowledge of who is working with which animals will 
lead to a useful exchange of information and/or specimens. For example, it seems 
ridiculous to m e that Doris si. still exists without proper naming. Please direct future 
solicitations to Opisthobranch Newsletter - CALL FOR SPECIMENS. This column may 
also be used to solicit specimens of species already described).

ERRATA TO BEHRENS' BOOK 



Dave Behrens has provided an errata to his book -- Pacific Coast Nudibranchs: A Guide 
to the Opisthobranchs of the Northeastern Pacific. The most significant errors lie in 
the oversight of Lambert (1976) making some of Dave's northern range limits a little 
short. Other errors are minor, even a few US/Canadian border disuptes over Vancouver 
and Puget Sound. Errors in capitalization and minor punctuation are left out here. 
Corrections are underlined, except for deletions, which are noted.

PERSONAL NOTES 

From Jeff Hamann: "I made an interesting trip to Cedros Is. in August. ,My wife, 
parents, 3 brothers and 1 year old daughter spent a week aboard a friend's boat, the 
Kalinga. We dove the southern end of the island and found 13 species of nudibranchs. 
The two worth mentioning were a new chromodorid and a range extension for an 
unnamed coryphelid. I brought the chromodorid home and Jim Lance is working it 
over. We also found a new, species which I've sent to Dave Behrens. The other 
species are more what you'd expect: Chromodoris macfarlandi, Dendronotus frondosus, 
Doto kya, D. amyra, Eubranchus rustyus, Facelina stearnsi, Flabellinopsis iodinea, 
Polycera atra, Hypselodoris californiensis & Cadlina flavomaculata. 

Grace & Tom Cockburn had their first child, a boy, Brian Andrew, on December 27, 
1980. Congratulations! 

Dr. S.A. Mileikowsky died suddenly on September 12, 1980. His works included 
seasonal dynamics of pelagic larvae of bottom invertebrates, and particularly 
breeding and larval distribution of Pteropoda. 

Bob Burn identified the dorid on Carlson & Hoff 's Christmas card as Chromodoris 
bullockl Collingwood, 1881 which has also been found in Northern Australia. 

From Hillary H. West: "I am currently an assistant professor of biology at Illinois 
State Uniiversity. In 1980 I received my Ph.D. from Northeastern University, Boston, 
MA. My thesis work was an investigation of chloroplast symbiosis and development of 
Elysia chlorotica a local salt marsh ascoglossan. Currently Dr. June Harrigan (of 
the NITT Biophysics program at Woods Hole) and I are collaborating on a study of the 
inheritance of variable reproductive modes in this animal using laboratory crosses." 

Dr. Itaru Usuki is now working in the field of Protozoology and is not doing any 
opisthobranch research. 

From Jeff Hamann: "I've finally finished sorting slides from Aruba. I also used 
Jim's [Lance] great library to identify most of them. I had all three of my brothers 
collecting with me & we came up with a grand total of 22 species. Snorkelling proved 
to be most productive as there is little or no tidal throw & only 3 specimens were 
collected in over 10' of water. Elysia cauze, Elysia ornata, Oxynoe antillarum, 
Aplysia dactylomela 2 Berthellina quadridens, Pleurobranchus areolatus, Aglaja 
evelinae, Aphelodorxs antillensis, Chromodoris clenchi, Hypselodoris ruthae, 
Dendrodoris krebsi, Platydoris augustipes?, Siraius kyolis, Hexabranchus morsomus,
